Question

Name the three effect of magnetc electric current.​

Answer 1

The direction of the force depends on the direction of the current that flows through the conductor. You can find the direction with the simple right-hand rule, which states that: the index finger points in the direction of velocity ‘v’, middle finger points to the direction of magnetic field ‘B’ and the thumb points in the direction of the cross product ‘F’. The magnetic field can be denoted by

F⃗ =qv⃗ ×B⃗  

A magnetic field is formed around a conductor when current flows through it which means it acts like a magnet. We also know that in magnets, unlike poles attract and like poles repel each other.

We know that in magnets like poles repel and unlike poles attract each other, so depending on the direction of the magnetic field induced, the conductor will either get attracted to or get repelled by the permanent magnet.
